✦ Synopsis

In the title compound, C 20 H 23 NO 12 , the pyranoside ring adopts a 4 C 1 chair conformation, with all substituents oriented in equatorial positions. The endocyclic C-O-C angle is in agreement with the geometry of the equatorial glycosidic bond, typical for the -d-4 C 1 pyranoside conformation.
